1-  Like new 20 rds fired Bushmaster custom shop 20 inch 1-9 twist chrome lined HBAR barreled upper assembly with Hogue free float handguard. Barrel is stamped BFI 5.56 NATO 1/9. This has M-4 ramps. Includes charging handle but does not include BCG as was purchased without.  A-2 FH has thin early Colt style split washer not a crush washer. Has rifle non F marked FSB. This had never been mounted on a lower receiver since purchased new and just checked on a couple lowers to insure fitment before listing for sale. Locks up perfectly.  $535 shipped / insured  to lower 48 CONUS only no  HI or AK.  

I can only accept United Stated Postal Money Orders, cash or certified check for payment. Apologies but I have zero electronic payment capabilities. I will only ship where legal to do so and is the buyers responsibility to adhere to state and Federal regulations pertaining to purchase or ownership of this item.  Item sold as is.

Only way to get the FSB with bayo lug was to order it this way. Basically a V match with a milspec FSB, not a shaved / pinned block and couldn't get the Hogue FF on the NM assembly.  Upper assembly has PN BUR A3 20 at a  cost of $515. A Hogue PN  15002 FF 79.95, 8448517 CH 26.50, SGW -09 rd HG cap 6.50, 8448577 early lock washer .60, parts installation / build charge was  free and shipping $16.50,  actual cost was $645 delivered back when they didn't collect tax.  These have an excellent reputation for varmint slaying and target accuracy.

*** I fired 20 rds 6-4-26, upper was unfired since originally purchased from Bushmaster.  Upper shoots lights out. Took 3 rds to zero optic and then nailed 6 inch steel plate 17 out of 17 at 115 yds. I used 25 grain Benchmark with 55 FMJ at 2.245,and a budget Bushnell  3x9 optic, nothing special. Can include the BCG, a like new M-16 chrome lined parkerized carrier ( Bushmaster stripped PN 844507) with a staked Young mfg chrome carrier key ( only 20 rds test fired), used Colt MPC stamped bolt and Colt M-16 firing pin, cam pin and FP retainer I used for testing for an additional $75 with purchase of upper. *** Will post pic of BCG as a reply.

Want a new, like new 15 plus year old Bushmaster upper that shoots lights out, no need to look elsewhere, cost is simply that, they don't make them like this anymore with sight blocks , bayo lugs etc.
